基于信用风险和流动性风险的银行市场结构对银行市场均衡的影响模型

借鉴Lucchetta提出的银行市场结构表示方法和研究思路,在假设信用风险和流动性风险都是不由银行自身决定的外生变量的条件下,以信用风险和流动性风险的不同组合表征银行市场结构,以自身收益最大化为银行决策目标,建立恰当的数学模型从理论上研究银行市场结构对银行市场均衡的影响。研究结果表明,在以信用风险和流动性风险度量的任何集中度的银行市场中,都既存在使银行市场运行良好的市场结构,也存在使银行市场体系崩溃的市场结构;当银行市场结构变量位于某个区间时,不同的流动性风险分布和不同的银行集中度将对银行市场均衡产生显著不同的影响。要使银行市场体系持续健康运行,就必须保持合理的银行市场结构。

Modelling the Effect of Bank Market Structure on Bank Market Equilibrium Based on Credit Risk and Liquidity Risk

This paper sets up an appropriate mathematical model to theoretically research the effect of bank market structure on bank market equilibrium with maximizing return as banks' decision objective,according to Lucchetta's idea that the market structure of banks represents research methodology and approach,under the hypothesis that credit risk and liquidity risk are exogenous variables which are not determined by banks themselves,through various combinations of credit risk and liquidity risk to express the bank...
